Just came across this product: http://www.healthyseal.com/ . Never used it and don’t know who has, but the concept is great: a spray-in-place foam insulation made from soybeans!!!! No need for petroleum based formulas and what they require re respirators, oil imports, etc. Open cell .5 density and closed-cell 1.7 density. Cool idea, wonder if it works in practice.

Thanks for bringing that up, Cloud. Sounds interesting.
But I'm with you in wondering how good the stuff is. And hopefully it will be less expensive to icynene.
